Myo Connect displays "Unable to listen on port 0" error when launched

The unable to listen on port 0 error indicates that another a service or application running on your computer is using the same WebSocket port as the one that Myo Connect uses or Myo Connect is already running.

Try shutting down other programs or services you have running before launching Myo Connect.

Check the Mac menu bar or the Windows system tray for the Myo Connect icon to see if Myo Connect is already running.
